Hi Yufan, Sorry this did not resolve your issues. I believe I see the issue now and am sorry I did not catch this earlier. In your previous screenshots for the configuration of the RFDC the PLL reference clock input is set to 245.76 MHz when it should be set to 491.52 MHz. The LMX file you are using, “rfsoc4x2_LMX_REF_245M76_OUT_491.52.txt”, in your init method to the RFDC is providing an output of 491.52 MHz. The input reference to the LMX is 245.76 from the LMK that provides an output reference of 491.52 to the internal PLL of the RFDC. This reference for the internal RFPLL is what is being configured in the drop down when you change it from 245.76 to 491.52.MHz. Try this and let us know how it goes for you.
